Catching insects, picking leaves, making specimens... There is such a treasure course in Zhongliang University, which moves the classroom to the wild. Sophomore students will take part in the first semester of each school year. At the end of the second semester, a 6-day internship was conducted to collect animal and plant specimens, field observation records, and gain an in-depth understanding of the importance of protecting biological diversity and rational utilization of biological resources. This course is , a special course of of the School of Life Sciences - "Biology Field Practice" . The course has been open for nearly 20 years and has always been loved by students.
The West Tianmu Mountain National Nature Reserve has superior natural conditions and rich biological resources. It is a rare "treasure house of species genes". “Choosing the West Tianmu Mountain National Nature Reserve for biology field internships allows students to become familiar with and understand the composition and characteristics of local animals and plants in a short period of time, and to understand the relationship between the living environments of different animal and plant species. Adaptability." said Professor Xu Aichun, the main person in charge of the course.
We are serious about catching bugs! The curriculum of
is rich and interesting, including the collection, identification, production and ecological inspection of animal and plant specimens, Tianmu Mountain forest vertical band spectrum inspection, etc. “During the days of field internship, if you see students holding insect catching nets , squatting or jumping up, sometimes slowly, sometimes quickly, don’t doubt that these are students collecting animal species! "Wu Qian, one of the teachers who led the team, said that despite the hot weather, the students' enthusiasm has not diminished at all and they are extremely excited every day.
lamp lure is another special part of this course. At 7 o'clock in the evening, the students will go to the balcony on the top floor of the accommodation. There will be a white cloth and a few dimly shining electric lamps on the balcony. Next, they will quietly wait for the phototactic insects to "come" on their own. After a while, many insects will appear on the white cloth uninvited. At this time, you need to boldly step forward, open the bottle cap, and put the insects into the poison bottle. "It was the first time I saw so many bugs. I was a little scared at first. Later, through the cooperation of my hands and the bottle, I became more and more proficient and no longer scared." Fu Wenjie from Class 20 Animal Inspection Class 1 said.
Immortal Peak, climbing to the top is a must!
The vertical band survey in the Tianmu Mountain forest is an extremely physically demanding activity, but the students are eager to try it and set the goal of climbing to the top. Walking along the mountain road, students can observe the vertical spectrum of the forest along the road while ensuring safety: at the foot of the mountain is a large amount of evergreen broad-leaved forest; at an altitude of 850-1100 meters, it is a mixed evergreen and deciduous broad-leaved forest; Climb further up and you will see the deciduous broad-leaved forest ; the deciduous dwarf forest is distributed in the highest area of Tianmu Mountain. Chen Qi, from Class 1, 20, walked in the first echelon at first, but the uneven road up the mountain gradually slowed her down, but it also gave her more time to observe the vertical band spectrum of the forest. "The main shrubs include Chinese hydrangea, Pittosporum acuta, Elaeagnus elegans, etc., and the herbaceous plants include Aster three-veined, Aster chinensis, Variegated orchid, etc." 20 Sheng Gong 2 Pan Xiru from the class also observed various plants along the way.
After 2-3 hours of climbing, the students will arrive at the resting point. At this time, it is up to the students to decide whether to go straight down the mountain or go up to the top of Xianren Peak. Chen Zhuoyu, who was in class 2 of 20 students, chose to continue climbing to the top. The moss-covered mountain road is prone to slippage and wrestling. On the way, the students "help each other" from time to time and move towards the same goal. "When I reached the top of the Immortal Mountain, I felt a sense of pride for my persistence and victory," Chen Zhuoyu said.

Time flies when making specimens!
"Moths, butterflies, dragonflies and other insect specimens need to spread their wings, and then press them with sulfuric acid paper . After being fixed with pins , put them in a dry place and remove them after the specimens are completely dry." Teacher Xu Aichun patiently explained the process of specimen preparation. Pay attention and demonstrate to the students at the same time. The students were attentive, sticking their heads out from time to time to take a closer look, for fear of missing any information. This is the "classic picture" of the taxidermy session every year.
Professor Xu Aichun guided the preparation of specimens
"The students are particularly interested in making specimens and are reluctant to leave the table at the end of the day." Instructor Yu Xiaoxia said that each group needs to make at least 00 animal specimens and 20 plant specimens. This is a big challenge for the students. "Preparing specimens gives each class and group an opportunity to communicate, and everyone gradually becomes familiar with it in the process." Wang Jiali from Class 20 Animation Examination 1 was deeply impressed by the specimen preparation process. The students not only learned from each other's specimen preparation techniques, but also You can also make new friends, "This feeling is amazing."
Display of finished specimens
"We must capture on demand" "We must release particularly rare species if we capture them" "We must focus on strengthening our own ability to survive in the wild and adapt to nature ability" and "strive to become biology professionals who adapt to the development of the times"... After the course, Xu Aichun will carefully review the students' internship experience. Whenever he sees these, he knows that compared with traditional classrooms, allowing students to When we go out of campus, we can gain more things, which also gives this course an extra layer of meaning.
